This app note is about protecting the input side of a regulator from overvoltage by choosing a capacitor with enough ESR to damp the LC network at its input, possibly formed by a long cable to a wallwart, etc.

Linear's website has become less user-helpful than in the past -- even as Switcher-CAD has gotten better. Downloads of their apnotes and product folders takes much longer than a year ago (and my ISP has doubled its own speed in the same time period.)

I have notice this also, its unbelievable slow to start downloading pdf's. If they happen to work at all.
